Description
Technical Field
The utility model relates to the technical field of twist drills, in particular to an anti-falling twist drill rod.
Background
The twist drill is a consumable tool accessory for mining, is a high-efficiency twist drill for coal seam drilling, is usually made of high-quality carbon steel, and is generally composed of a working part, a handle and a neck, wherein the working part comprises a conical cutting part with a cutting edge and a cylindrical guiding part with a spiral prismatic belt. It mainly takes on the cutting tasks and guiding functions. The handle part is provided with a straight handle and a Morse cone. Is the clamping part of the first drill bit and is used for transmitting the torque and the feeding force required during drilling, and the neck part is the connecting part of the working part of the first drill bit and the handle part and is used for marking trademarks, the diameter of the first drill bit, materials and the like. The electric drill is suitable for the use of electric coal drills, and is an ideal necessary tool for coal exploitation. The coal drill pipe is used in combination with various types of coal drills and air drills. The method has the characteristics of high drilling speed, good drilling stratum and high drilling efficiency, reduces the influence of drilling construction on the coal seam exploitation progress to the greatest extent, and is widely used for drilling and exploitation of coal mines and gypsum ores.
As is well known, drill pipes currently used in coal seam drilling in the well are shiny drill pipes and twist drill pipes (including spiral drill pipes) for coal exploration, water exploration, gas emission, protrusion prediction and the like. The adopted chip removing method is spiral mechanical chip removing (namely dry drilling), compressed air chip removing by compressed air and compressed water chip removing, and chip removing by matching the spiral with the compressed air (or the compressed water). Twist drill rods are often used for underground coal mine construction of various water exploration and drainage drilling holes, exploration and construction drilling holes, discharge holes and other drilling holes. The traditional twist drill rod is provided with a cylindrical pin at the front part of the square head tenon, and the bottom of the pin is connected with a spring and is used for clamping a round hole on a tenon hole at the tail part of the drill rod so as to prevent the drill rod from falling off. In addition, a pin hole is formed at the position away from the root of the square head tenon, a round hole is formed at the corresponding position of the tenon hole at the tail part of the drill rod, and an iron wire penetrates through the pin hole and the round hole to be connected when the drill rod is connected. The drill rod is often broken at the weak stress position of the pin hole at the root of the square head tenon in construction. The drilling construction efficiency is severely restricted, and in addition, the drilling difficulty of some hard stones is high, so that the drilling strength needs to be improved urgently.
Therefore, we propose an anti-drop twist drill rod.
